Abstract

596,981. Snap-action switches; retractive switches. FIRST INDUSTRIAL CORPORATION. Feb. 1, 1945, No. 2575. Convention date, Jan. 28, 1944. [Class 38(v)] [Also in Group XXXII] The main-spring 35 of a snap-action switch of the character disclosed in Specification 419,917 has compression members 42, 43 anchored in legs 32, 33 of a plate 31. A trifurcated auxiliary spring 45 has its central leg 46 attached at 49 to the free end 44 of the main-spring 35, whereas the side legs 47, 48 are secured under the heads 53 of movable contacts 51, 52. The shanks of the latter pass freely through the end 44, which, when the spring 45 is unstressed lies midway between heads 53, 54. In moving from one position to the other, the end 44 first unstresses the spring 45, whereupon the heads 53 disengage and the whole moves together until heads 54 touch the lower contacts, further movement of end 44, until it engages the backs of heads 54, producing stressing of spring 45, so preventing chattering due to rebound.
